The latest version of software for the Oculus Rift is rolling out with support for Mixed Reality capture and a re-designed interface for future updates and a new Home environment. There is also multi-language support. The Oculus store now has support for 360º only apps which allows different sensor set ups, using dual sensors, one in front and one behind the user.
Oculus expects developers to have to modify their apps to support Mixed Reality.
